NGK 5950 BPM6F Standard Spark Plug 14mm Copper Core Nickel

The NGK 5950 (BPM6F) Standard Spark Plug is a nickel-electrode, copper-core replacement spark plug built to NGK's original-equipment standards. NGK is a long-time OE supplier, and this plug is a good choice for engines that originally came with standard nickel alloy plugs. It is also commonly used in small engine and power equipment applications such as chain saws.

Key Features:

• Solid copper core improves heat dissipation and conductivity across a wide heat range
• High-grade alumina silicate ceramic insulator adds strength and helps with heat transfer
• Trivalent metal plating resists corrosion and seizing, so installation and removal are easier

• Triple gasket seal helps prevent combustion gas leakage
• Corrugated insulator ribs help prevent flashover
